SSL_get_fd(3) OpenSSL SSL_get_fd(3) NAME SSL_get_fd - get file descriptor linked to an SSL object SYNOPSIS #include <openssl/ssl.h> int SSL_get_fd(const SSL *ssl); int SSL_get_rfd(const SSL *ssl); int SSL_get_wfd(const SSL *ssl); DESCRIPTION SSL_get_fd() returns the file descriptor which is linked to ssl. SSL_get_rfd() and SSL_get_wfd() return the file descriptors for the read or the write channel, which can be different. If the read and the write channel are different, SSL_get_fd() will return the file descriptor of the read channel. RETURN VALUES The following return values can occur: -1 The operation failed, because the underlying BIO is not of the correct type (suitable for file descriptors). >=0 The file descriptor linked to ssl.
